Title: Improvements in and relating to the ventilation of enclosures or the like
IPC: F24F7/08
Filed: 1928-04-04
Abstract: 297,293. Carrier Engineering Co., Ltd., (Carrier, W. H.). April 4, 1928. Forced ventilation; ventilating-pipes, arrangements of.-Conditioned air in small quantities is ejected at high velocity into large enclosures, such as theatres, so that the ejector stream moves across the enclosure in such manner as to cause a. uniform and definite movement or circulation of the body of the atmosphere in the enclosure, thereby dissipating the momentum of the entering air without the creation of uncontrolled currents in the enclosure. Ejector nozzles 21 are provided in one or more laterally-arranged pipes 19 connected to the ends 11, 12 of branches 10<a> leading from a conduit 10. The air is extracted through ducts 13, 15 leading to a vertical conduit which is forked at its upper end, one branch exhausting to the outer atmosphere and the other 16 leading to the supply side of the delivery fan 9. A spray device 18 and heater 22 may be disposed in the fresh air conduit 17. The nozzles 21 on each of the pipes 19 deliver a substantially horizontal stream of air across the enclosure, and the size of such nozzles is such that the air stream does not impinge upon an obstruction such as the proscenium arch 2 of a theatre. The pipes 19 may be housed behind the decorative plasterwork of a theatre. Specifications 133,897 and 273,069 are referred to.

Filed: 1923-04-16
Abstract: 219,370. Marks, E. C. R., (Dunn Manufacturing Co.). April 16, 1923. Bore-hole apparatus. - Means for use in wells for lifting casings, tubing, or rods comprises hinged members adapted to embrace the casing &c. and connected to suspension means, and a spring-operated latch to lock the hinged members together, the spring tending to force the hinged members apart before they reach their fully closed position. In Fig. 1, members 1, 2, connected by a hinge 3, are locked by a latch 22 pivoted to the member 1 and engaging a nose 28 on the member 2 under pressure from a spring 26. The nose 28 has a curved part 31 engaging a part 32 of the latch when the members 1, 2 are only partially closed, the reaction between these surfaces, under the pressure of the spring 26, tending to force the members 1. 2 apart. Handles 29, 30 are provided on the latch and member 2 respectively. In Fig. 3, the members h, j, are connected by a pivot pin 39 which may carry a spring tending to force the members h, j apart. A latch 42 pivoted to the member j is pressed by a spring 47 into a recess 40 in the member h; when the members h, j are only partly closed, the spring 47, forcing the latch against the member h, tends to force the members h, j apart. A shaft carries a projecting arm 55 and may be turned by a pivoted handle 62 to cause the arm 55 to move the latch out of locking position; the pivoted handle 62 may be held in inoperative position by engagement with a projection on the part h.

Abstract: 288,336. Schweder, W. April 6, 1927, [Convention date]. Discharging; cooling discharged materials.-In a process of producing a mixture of coal gas and water gas, the glowing coke from the coke oven is transferred to a water gas generator in which it is gasified. The hot coke discharged from the distillation chamber 2 is conveyed in trucks 10 to a water gas producer 4 to which steam is admitted by pipe 5. The generator 3 for heating the chamber 2 is charged with coke and fed with a part of the water gas produced through pipe 19. The coke in the generator 4 cooled by the steaming may be partly removed but may be periodically blasted up with air from pipe 6 when a greater supply of water gas is required, and the entire charge of coke may be consumed in this way. The gases from hot blasting are cooled in pipe 25 and used to dry-cool the coke in a container 21, and the gases thus re-heated are passed by a. pipe 27 through a waste heat boiler 28 and by a pipe 29 to a chimney 30.

Abstract: 723,351. Frequency measuring. GENERAL ELECTRIC CO., Ltd., and HARROLD, A. E. April 28, 1953 [April 28, 1952], No. 10663/52. Class 37. In a device for measuring the difference in frequency between two oscillators with or without means for exercising a control at a predetermined value of such difference, the oscillation frequencies are multiplied and then mixed and the beat-frequency current passes to the primary 7 of a transformer 8 through a high resistance 6 which maintains the current substantially independent of frequency. The voltage induced in the secondary 9, which is thus proportional to frequency, is rectified at 11 and the smoothed output across resistor 14 applied to the control grid 16 of valve 17, the anode current being measured in a meter 19 calibrated in terms of frequency. The meter may be replaced or supplemented by the winding of an electromagnetic relay which operates an alarm when the frequency exceeds a preset limit.

Title: Improvements in or relating to Sole-pressing Machines.
IPC: A43D35/00
Filed: 1918-07-03
Abstract: 129,110. British United Shoe Machinery Co., (United Shoe Machinery Corporation). July 3, 1918. Sole blanks, machines for; sole-laying; solelevelling.-To produce soles in which the ball portion is separated from the shank by a well-defined line forming a sharp " break " at this portion of the sole, the forms 5, 6 of a moulding-machine are actuated to impart a series of progressively increased pressures to the sole with a reduction of the pressure prior to each increased pressure. The lower form 6 is mounted on a slide 30 carried by a vertically movable head 9, which is actuated through toggle-links 7, 8 and a roll 11 from a cam 10 on a shaft 13. This cam is provided with operative portions 14, 16, 19 to apply first a light, then a heavier, and afterwards the heaviest, pressure to the sole, and with recessed portions 15, 18 to relieve the pressure after each application; the shaft 13 is automatically stopped after the cam has made half a revolution, the surface 16 then being operative, but the cycle of operations is completed during a single rotation of the shaft. The forms 5, 6 are arranged so that they first clamp the sole in the region of the " break," as shown at 25-25 in Fig. 3, and as they continue to move toward one another, they are moved relatively in a lengthwise direction until they register exactly in the final pressing position; this causes the sole to be squeezed by the forms into the space of the ball line to form the " break " without reducing the thickness of the sole or straining the fibres unduly. For this purpose, yielding connexions are provided between the slide 30 and its actuating-lever 34, which is pivoted at 36 to the head 9, and is formed with a cam-slot 38 to receive a roller 40 on a bracket 42 secured to the toggle-arm 8; the roller 40 rides into the upper part of the slot when the form 6 is near the lower part of its rising and falling movements, to move the slide to and from a position of presentation to an operative position in alinement with the upper form. The yielding connexions comprise a U-shaped member 58 pivoted at 56 to the lever 34, and received between the arms of a second U-shaped member 60 pivoted on a shaft 62, which is carried by lugs 64 depending from the slide 30 and through elongated slots 66 in the arms of the member 58. An adjustable compression spring 68 normally holds the members 58, 60 with the shaft 62 at the left end, Fig. 1, of the slots 66; but, when the pressure is applied to the sole, the shaft 62 slides in the slots, and the spring is compressed. The stationary form 5 is adjustable in its head 72 by means of a grooved screw 74 engaging an upturned end of an extension 73 of the form.

[Class 103 (vi)] In order to prevent the unequal distribution of the static load upon the two axles of a motor bogie 16 due to the overturning torque produced by the tractive force of the motors, the bogie 16 is coupled to the vehicle body or underframe 15 by means of an inclined connecting rod 14 having spherical pivot bearings at each end, in addition to its normal central supporting pivot bearing 5, 12. To ensure that the tractive effort is exerted on the rod 14, the bearing block 12 may slide between fore and aft projections 24 on the bogie. In a modification, two connecting rods 21 and 22 are used, their axes meeting at the central pivot of the bogie 23, and springs 25 may be inserted between the bogie and the vehicle frame to resist lateral displacements of the bogie.
